Kansas City Chiefs? star tight end Tony Gonzalez recently received the results of the x-rays taken on his foot and to his delight, the x-rays came back negative. Coach Dick Vermeil is not sure when Gonzalez will return to practice and with backups Jason Dunn and Kris Wilson already injured, Vermeil has been forced to go deep into his bench calling on Edwin Thompson and Mike Kallfelz. ?Neither of them have played in the National Football League,? Vermeil said. ?The kids struggled last night but they gave us the best that they had and enabled us to practice.?
